Duet3 cant connect if z probe present
-
Hi> I have received today a nice new inductive sensor. I was using one with a sensing distance of 2 mm for about 2 months with no problem but sometimes due to a nasty overhang the probes chrases with the print so now I have decided to move into a 4 mm distance inductive probe.
But Im having this problem: the raspberry pi now cant connect to the duet (my configuration is a duet3 connected woth a raspberry pi 3)
Nothing changed on my config.g since the sensor basically uses same pins. If I discpneects the sensor, the system starts with no problem, If I connect the sensor, the DWC cant connect to the duet board.
Any ideas where the problem can be with this sensor? It is the same manufacturer than my previous sensor. voltaje requested is the same.
Sensor is connected to:M558 P5 C"^!io3.in" H5 F120 T18000
Also, I have used a second duet3, and it is not showing this problem, both of them using the same sensor, same config.g
-
@tinchus Are the two duet boards the same revision?
-
@gloomyandy yes 1.01
-
How are you powering the Pi and the Duet3?
Can you please post the results of M122 and M98 P"config.g" plus your config.g for completeness?
-
@phaedrux I cant get you the M122 results because the raspi never connects to the duet when it fails, so I can never input any command into the console.
Power: rasp is being powered independently of the duet. Duet board gets it power from a 24V source (300W) and the raspi from the same PSU but with a different cable. The jumpers on the duet board are configures to this setup. But since your comment, I just did and experiment wich is confusing to me: I jumpered the pins that are suposed to be used in case the duet board is powering up the raspi.... and that seems to solve the problem. But this is not how things are being pwered, as I said, the raspi is being powered directly from the PSU and the duet from the PSU, none of them is powering the other . Weird, so this seems to be a solution but still I think something is wrong, I dont think this is normal si ce the other board I have doesnt have this problem.

Can you do up a wiring diagram or some photos of the wiring?
Ground loop maybe, or voltages going where they shouldn't be.
-
@phaedrux Thank you. Ground loop was the problem!
Problem solved. There was a screw in the PSU breaking the insulation. -
@tinchus thanks for letting us know what the resolution was.
